'A. CORPORATION OF DELAWARE BOX AND METHOD OF MAKING SAME Application filed November 19, 1930. Serial No. 496,658.

My invention is particularly adapted for use in the manufacture of boxes from fibre board and comprises the blank used, the meth-. d of forming the box and the improvements secured in the box when it is erected.

An object of my invention is to provide a blank which is simple and easy to manufacture, causes a minimum of waste of material, and which can be readily setup or erected in into box form by unskilled labor and when so erected possesses a maximum of rigidity and a finished substantial appearance.

Another object of my invention is to provide simple and positive locking means which are a part ofand cooperate with the box members to positively lock the same in erected position.

'My invention provides a blank which can be coated when flat with an adhesive such as glue, silicate of soda, collodion or a heated asphaltum compound, and then erectedinto a laminated box structure with the adhesive coating between the box members.

My invention provides a blank in which the outer lamination may be folded into box section form and thereafter the members comprising the inner lamination may be individually folded into position within the outer section until the box is completed. A double ply box is thus obtained.

My construction eliminates much of the difiiculty experienced in the manufacture of laminated boxes because a precise fit of the separate box sections is not necessary and the difiiculty of assembling one series of mem bers as a whole with another series of members already erected into box section form is largely obviated. This becomes of great importance when using a blank or blanks coated 4 with an adhesive, which from its nature is sticky and resists the sliding ofone member over another member. Likewise my construction is of marked advantage when using a reenforcing piece or blank between the lami 4 nations of the box, and permits the usev of a thick or bulky reenforce blank without difliculty. i

Due to the ease and accuracy with which my improved boxmay be erected, the slight 5 resistance encountered by the box members in going into proper position, and the provision made to automatically lock the members into position it is unnecessary to press the layers of my box over a form or die after folding, which is the usual practice with other types of laminated boxes. This afiords a great saving in machinery and equipment.

My box is well adapted for use as a cigar box, since it has a finished appearance and when constructed with a heavy reenforce blank, provides a wall of about the thick ness used in wooden cigar boxes. For this purpose I prefer to use a flat wooden cover hinged to the box and thus obtain a cigar box which is an exact replica of a wooden box, and has as much or more rigidity and a great deal more strength to resist breakage. In the accompanying drawings, Fig. 1 is a plan view of one form of my improved blank, cut and creased or scored, so that it can be erected to produce a box, and provided with members for use in automatically locking the p parts of'the box when same are set up in box form. Fig. 2 is a plan view of one form of reenforce blank which may be used in connection with my improved blank. Fig. 3 is a perspective view of the reenforce blank shown in Fig. 2. Fig. 4 is a perspective view of the blank shown in Fig. 1, partly folded.

Fig. 5 is a perspective view of the completed box. Fig. 6 is a perspective view to-a greatly enlarged scale of one corner of the box shown in Fig. 5 to make clear the action of the automatic locking means.

In the drawings like reference numeralsrefer to like parts. As illustrated in Fig. 1

a fibre board sheet is provided with the parallel creases 10 and 11 and with the parallel creases 12 and 13 vat right angles thereto. These four creases 10, 11, 12 and 13 define the bottom member 14. of the outer lamination of the box. lel creases 16 and 17 define one end wall 18 of the outer lamination of the box. The crease 19 and the creases 20 and 21 define the opposite corresponding 'end wall 22 of the box.

along the crease 10 and the end wall 22 is hinged to the bottom 14 along the crease 11. The crease 23 and the cuts 24 and 25 The crease 15 and the paral- The end wall 18 is-hinged to the bottom 14 define one side wall 26 of the outer lamination of the box. The crease 27 and the cuts 28 and 29 define the opposite corresponding side wall 30 of the box. The side wall 26 is hinged to the bottom 14 along the crease 12 and the side wall 30 is hinged to the bottom 14 along the crease 13. The member 31 between the creases 23 and 32 and the member 33 between the creases 27 and 34 form the upper edges of the side walls of the box. The member 35 between the creases 15 and 36 andthe member 37 between the creases 19 and 38 form the upper edges of the end walls of the box. The member 39 between the creases 34 and 40 is hinged to the member 33 along the crease 34 and forms one inner side wall of the box. The member 41 between the-creases 32 and 42 forms the opposite corresponding inner side wall of the box. The member 42 hinged to the member 39 along the crease 40 forms a part of the inner bottom of the box and the member 43 hinged to the member 41 along the crease 42 forms the other part of the inner bottom of the box. The member 44 hinged to the member 35 along the crease 36 forms one inner end wall of the box. The member 45 hinged to the member 37 along the crease 38 forms the op posite corresponding inner end wall ofit'he box. The corner-piece 46 is hinged to the end wall 18 along the crease 16 and the corner-piece 47 is hinged to the end wall v18 .along the crease 17. The corner-piece 48 is hinged to the end Wall 22 along the crease 20 and the corner-piece 49 is hinged to the end wall 22 along the crease21.

It will be noted that the edge 50 of the member 44 is longer than the crease 36.

. Similarly the edge 51 of the member 43 is longer than the crease 42. The edge 52 of the member 42 is longer than the crease 40 and the edge 53 of the member 45 is longer than the crease 38. This greater length in each case provides the additional stock desired to secure the automatic locking of all of the members of the box when the same is erected.

Figs. 2 and 3 illustrate a form of reenforce blank, 54 represents the bottom member having attached thereto the side wall members 55 and 56. Attached to the end of the side wall members are the end wall members 57, 58, 59 and 60.

Fig. 4 shows the blank of Fig. 1 in partly folded condition. The outer end walls 18 and 22 have been brought up into position and the corner pieces 46, 47, 48 and 49 have been folded into position. At this point the bottom 54 of the reenforce blank shown in Fig. 3 would be superimposed upon the bottom 14 of the partly folded blank with the side and end walls of the recnforce lying within the enclosure formed by the end walls 18 and 22 and the corner pieces 46, 47, 48 and 49. The outer side walls 26 and 30 are now brought up to position and the inner side walls 41 and 39 are folded over the adjacent corner pieces and the side walls of the reinforce blank. Placing the inner side walls in position will bring the inner bottom section 43 and 42 into position on top of the bottom 54 of the reenforee blank. The inner end walls 44 and 45 are now folded over the end Walls of the reenforce blank and pressed back at the corners until the inner end walls snap back of the inner side walls as shown in detail in Fig. 6. This completes the folding and locking of the blank into the finished box, shown in Fig. 5.

Referring to Fig. 6 it will be noted that the length of the edges 51 and 52 of the abnormal inner bottom members 43 and 42 causes the same to project under the edge 50 of the inner end wall member 44 and this locks the bottom members into position. Likewise the length of the edge 50 of the abnormal inner wall member 44 causes this edge to project past the inner side wall members 39 and 41 and this looks the inner end wall members into position.
